WINDOW-FRAM E.

SPECIFICATION forming part of Letters Patent No. 431,639, dated J' uly 8, 1890.

Application filed November 30, 1889. Serial No.332,069. (No model.)

.To all .whom it may concern: i

Be it known that I, BRUNO AS'CHENBACH, a citizen of the United States of America, residing at St. Joseph, in the countyT of Buchanan and State of Missouri, have'invented certain new and useful Improvements in Vindow-Frames; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

This invention relates to certain new and useful improvements in window-frames and sashes therefor; and it consists in the construction and combination of the parts, as will be hereinafter fully set forth, and pai'- ticularly pointed out in the claims.

The object of my invention is to provide a sash-frame with guide-strips, one of which is held rigidly in place, while the other is movable and is held in contact with the sashes by springs to prevent rattling thereof.

My invention also consists in providing the sash-guides or vertical strips with grooved rollers, over which the sash-cords pass, the guide-strips above said rollers being grooved.

My invention also consists in providing a' sash-weight vhaving a longitudinal recess,

within which the inner side of the sash guidestrip lies to effect the proper vertical movement of the-said weight, and thus dispense with the usual boxes.

In the accompanying drawings, Figure l is a front elevation of a window frame and sash, parts thereof being broken away to better illustrate the construction. Fig. 2 is a transverse section taken on the line cc .fr of Fig. 1. Fig. 3 is a detail perspective view of a section of one of the'guide-strips removed. Fig. 4 is a perspective view of one of the sashweights removed.

A indicates the window-frame, and B and B the upper and lower sashes. The windowframe A is preferably made up of top and bottom transverse pieces, outer vertical side pieces, and inner vertical strips o. a, which are parallel with each other, and between which are located the guide-strips C for the sash-frames. These guide-strips O C are either made up of a single piece or they may he made of a central strip O', to which are rigidly attached side pieces C2 and O3, the part OS being located above the Arollers D, which are `mounted upon a shaft passing through the central portion of the guide-stri p. The upper short sections O3 have their lower edges immediately above the pulleys or rollers grooved to provide,-in connection with the grooved faces of the rollers, a circular Opeliing, through which the sash-cord passes, thus permitting the lower edges of the upper sections to be placed very near the pulleys to prevent the sash-cords becoming displaced. The rollers D are loosely mounted on journals and rotate independently.

One of the guide-strips on one side of the window-frame is rigidly secured between the strips a a, while the opposite strip has at its upper and lower portions projecting lugs f, which are adapted to abut against the inner sides of the vertical strips a a and limit the inward movement of the guide-strip, and this movable guide-strip is pressed inwardly by springs g g, attached to the inner side of the outer casin g, the ends thereof bearing against the inner side of the guide-strip. By this construction one lof the guide-strips is movable inwardly, and will bear upon the sash so as to prevent rattling and at the same time make a tight joint, which will exclude air, &c. By having one of the strips movable the sashes can be readily removed.Y

One of the strips a on its outer edge is provided near its upper and lower ends with inwardly-projecting plates 7L, having perforations through which pins t' are passed, said pins also engaging with perforations 7c, formed in the upper and lower ends of the guidestrips, and when these pins are inserted the guide-strip will be held immovable. The movable guide-strip can be held inwardly or outwardly, as may be desired, by either passing the pin through the perforations, as explained, or simply letting it bear transversely across the rear edges of said guide-strips.

If desirable, the inner faces of the guidestrips which lie within the recesses in the IOO hiding the sash-cords when the sashes areV lowered.

It will be observed by the construction hereinbefore described that I dispense with Aboxes for the sash-Weights, and in order that said sash-Weights may move vertically in the l space provided therefor I provide the inner faces of the sash-Weights with longitudinal grooves or recesses w, in which theinner faces of each' of the guide-strips formed by the sections C2 C3 will lie, and as each of said guidestrips are separated from each other by the central portion C, hereinbefore described, the sash-Weights will move upon the projecting portions, and boxes therefor are dispensed with. It will also be observed that the sashes can be held in position so as to move easily up and down, that they may be locked against complete removal by causing one of the guidestrips to bear upon the same, and that the vertical guidestrips not only serve as guides for the sashes but also as guides for the sashweights.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a Window-frame constructed substantially as shown and provided with vertical slots or recesses, of guide-strips having inwardly and outwardly projecting side pieces located within said vertical reccsses and each composed of upper and lower sections, rollers secured to the central portion of said guide-strips between the upper and, lower sections of the side pieces, one of said' guide-strips being rigidly secured in place while the other is held by springs to bear upon the sashes, and sash-cords and weights,

substantially as shown,\and for the purpose set forth.

2. The combination, in a window-frame, of guide-strips provided with side pieces consisting of upper and lower sections, and grooved rollers between said upper and lower sections, the vedge of each upper section adjacent to the roller being recessed, substantially as set forth.

3. The combination, in a window-frame, of the guide-strips, the inner faces ofsaid guidestrips having concave recesses, grooved pulleys, weights, and sash-cords, substantially as shown, and for the purpose set forth.

4. The combination, with guide-strips having inner and outer anges, of sash-Weights having longitudinal grooves Which are adapted to iit over the rear flanges of the guidestrips, substantially as shown, and for the purpose set forth.

5. A Window-frame having vertical strips a a, guide-strips located between the same, said guide-strips havingacentral portion and side flanges, grooved rollers secured to the central strips on a line with the side flanges, the face of said roller and the inner face of the guidestrip having semicircular recesses, springs for holding one ofthe guide-strips against the sashes, and projecting strips for limiting the forward play of said guide-strips, sash-cords attached to the sashes land Weights, the

Weights being provided with longitudinal grooves, so that they will move upon the in- Wardly-proj ecting portions of the guide-strips,

substantially as shown, and for the purpose set forth. p

In testimony whereof I affix my signature in presence of two Witnesses.
